Remington 870 with the ISS (J-lock safety)

Special thanks to RomeoPapa for posting pic of the ISS (J-lock safety) of Remington 870 on Remington 870 Forum:

Here ya go. As shown, with the pointer aligned with the white dot, the safety cannot be moved to the “fire” position. You have to insert the key (the green thing) into the “J” shaped opening and rotate the pointer to the red dot. You can then take the safety off.

Remington 870 Tips & Tricks #6: Lock, Stock, & Barrel

New great video from Synchronizor:

While many aspects of responsible gun ownership focus on proper use of the gun, another key element is being able to prevent use of the gun by those who can’t be trusted with it.

In this video, I’ll be focusing on gun locks for the Remington 870. These are devices that attach to a firearm, rendering it incapable of firing. They will not prevent theft, and can certainly be defeated by a determined individual, so they’re not a replacement for a gun safe. However, they are inexpensive, portable, and generally effective in preventing easy access to a functioning firearm. There are always situations where any gun owner will need to be able to disable their firearms, and a gun safe may not always be affordable or available.

I’ll go over the capabilities and general philosophy of gun locks in firearm safety, and compare the characteristics of three different types: trigger blocks, action locks, and internal locks. I’ll show the devices I use for my 870 and other guns, and demonstrate some tricks I’ve come up with for increasing their effectiveness and adding safety or convenience.

Thanks to RomeoPapa for providing me with images of his ISS trigger assembly.

If you have any questions about this video, please ask. If you have some other preferred device or method for securing your firearms, please feel free to share it; I may well revisit this subject in the future. I’d also appreciate any comments on the format of this series; I’m still playing around with styles and programs, and I tried some new things in this video, so I’d love to hear feedback.

This continues my series of how-to videos with the Remington 870 shotgun. There are a number of other topics I have planned for future videos, but it’s a fluid list. I’d love to hear any suggestions you might have for video topics. If it’s something that I feel has already been thoroughly covered, I may point you elsewhere, but if it’s an interesting and feasible idea, I’ll add it to the list.

Shotgun Shooting: Lesson 1, Safety First

Due to many requests from readers, I am starting posting shotgun shooting lessons.

First of all, you need to understand safety rules. The best rules I know are the ones by Colonel Jeff Cooper.

Four Rules introduced by Colonel Jeff Cooper:

1. All guns are always loaded. Even if they are not, treat them as if they are.
2. Never let the muzzle cover anything you are not willing to destroy. (For those who insist that this particular gun is unloaded, see Rule 1.)
3. Keep your finger off the trigger till your sights are on the target. This is the Golden Rule. Its violation is directly responsible for about 60 percent of inadvertent discharges.
4. Identify your target, and what is behind it. Never shoot at anything that you have not positively identified.


You need to protect your shotgun during transportation. Most sights are fragile, especially with fiber optic inserts. Also, it is possible to scratch finish of your shotgun.

You can read more in my article: Shotgun Carrying Cases.

Good case enables you to have all necessary equipment: earmuffs, glasses, belt, shell caddies, cleaning kit, timer, knee pads, chokes etc.


Take shotgun out of the case only vertically. This way, you won’t point your firearm into unsafe direction.

Always carry a firearm on a range with muzzle pointing up. Shotgun must be unloaded, load it only before shooting. Always check a firearm is unloaded after each training.

Firearm checking procedure:
1. Unload magazine tube and chamber.
2. Make visual and touch inspection.
3. Hammer down, open action.


Shooting Hearing Protection (Earmuffs, Electronic Earmuffs, Earplugs, Combat Earplugs)

Ear amd eye protection are must have for all shooters. Shooters and spectators must wear earmuffs/glasses on the range. Eye or ear injury is very easy and cheap to prevent, but very difficult and expensive to cure once it has happened. Always wear eye and ear protection.

Attention: Regular eye glasses will not help to protect your eyes when using a shotgun, and even can cause worse injury when fragmented. Always use proper ballistic glasses.

Remember, the noise level of the shotgun shot is more than 150 dB. The threshold of pain is considered to be 140 dB. This means that shooting without hearing protection can cause sudden hearing loss with complications.

Tapco Shotgun Chamber Safety Flag

Tapco Shotgun Chamber Safety Flag
Tapco Shotgun Chamber Safety Flag

Safety flag is inexpensive but very useful tool. Chamber safety flag shows others that your shotgun is unloaded and chamber is empty. That makes everybody comfortable.

Safety flags are mandatory on competitions of a high level and with big number of competitors. You can carry your shotgun ONLY with safety flag installed.

Tapco Shotgun Chamber Safety Flag is made of bright polymer composite. It fits into the chamber of a shotgun perfectly. Very simple and useful tool. I recommend having several spare flags because they can get lost and you will have to buy one on the range (where they sold at ridiculously high price).

Remove Before Flight Shotgun Chamber Safety Flag

There is one modification which will make your safety flag look terrific! Just add a simple $2 “Remove Before Flight” keychain to your safety flag and here’s how it will look like:

This also serves one more purpose. It is much more difficult to loose chamber safety flag with bright red keychain. This is funny but useful addition to your chamber safety flag! :)
